Peak flow question

[Tinkz]

Hi all,

On a peak flow what is the % difference between 500 and 550?

I'm always at around 500 before salbutamol/ symbicort and always 550 aftwards? Tia 😊

I would say it had increased by 10% after your inhaler

Thanks for response butterfly, so would a 10% increase indicate that I have obstruction of some sort? (I'm still undiagnosed) would that be typical of asthma ?
